From Colossal Cave to The Walking Dead: The legacy of Interactive Fiction

The enormously popular Walking Dead video game series can trace its lineage directly back to the dawn of video games

One of the best Mac and iOS game series of the past couple of years is based on The Walking Dead, the popular graphic novel and TV series. Developed by Telltale Games, it's a point and click adventure game. It's thoroughly modern, featuring top-notch voice acting, a 3D engine and great production quality. It can also trace its roots back to some of the earliest popular computer games, a genre called Interactive Fiction, or IF for short.
